KlT FOR PHOTOGRAPHlC-PLATE HOLDERS.

SPECIFICATION forming part of Letters Patent No. 717,384, dated December 1902- Application filed May15, 1902. Serial No. 107,422. (No model.)

To all whom it may concern:

Be it known that I, AUGUSTINE GAFFNEY, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Kits for Photographic-Plate Holders; and I do hereby declare the following to be a full, clear, and exact description of the same, reference be ing had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention has for its object to provide a kit or appliance to be used in connection with photographic plate holders, whereby smaller plates may be held and used in plate-holders adapted for those of larger size; and it consists in an improved device which is simple and cheap in construction and which may be readily applied to the holder in daylight and the photographic plate afterward applied in the dark room Without the necessity of manipulating or adjusting small parts, all as will be hereinafter described.

In the drawings, Figure 1 is a perspective view of a kit constructed in accordance with my invention. Fig. 2 is a longitudinal sectional view of the plate-holder, showing the kit in position.

Similar reference-numerals in the two figures indicate similar parts.

The kit or attachment embodies a body or plate 1, preferably of metal, of a size which will fit and be retained in a plate-holder by the usual holding appliancessuch, for instance, as the stationary ledge or flange 2 and the movable recessed bar 3, (see Fig. 2)-said plate 1 being stiffened and prevented from buckling or cockling by having the longitudinal corrugations eat the sides and the transverse corrugations or beads 5 at the ends, the latter forming the thickened edges cooperating with the securing parts of the plateholder or containing-casing.

6 indicates ears or projections out from the body of the plate 1 near one end and turned upward and having their ends extending above the surface, and at the sides are arranged ears, lugs, or projections 7, cut from the plate and extending vertically.

Near the end of the plate 1, opposite the lugs 6, a loop or bridge 8 is struck up, beneath which extends a shank 9, formed intogrally with a bow-spring 10, having at its end the lugs 11, adapted to project over the edge of the photographic plate 12 to retain the latter in position. The spring is preferably formed separate from the plate 1, and the shank is prevented from withdrawal from the loop by any suitable means-such, for instance, as by indenting the body oftheplateland theshank 9 by a prick-punch, as shown in Fig. 2; but they might be otherwise secured, if desired.

The construction described is such that the kit may be applied to the ordinary plateholder in the same manner that the photographic plates are ordinarily applied thereto, and the smaller-sized photographic plate 12 may be inserted by placing the end of the plate beneath the lugs 11 on the spring, then forcing the latter back until the end of the plate can be dropped beneath the lugs 6, when the spring will force the plate into proper position and the lugs 7 will efiectually prevent lateral movement at both ends. The device as a whole is very simple and cheaply made from stamped metal embodying only two parts and may be supplied at a nominal cost, so that the user is able to use plates of the size for which his holder is adapted or of a smaller size, as desired. The beads or corrugations5 at the ends not only stiffen the plate 1 and preventits bending laterally, but are of substantially the thickness of the photographic plate for which the holder is adapted in order that the kit may be positioned by the same means that are used to secure a glass plate.

I claim as my invention- 1. An attachment or kit for photographicplate holders consisting of a base-plate having the corrugations at the ends and sides and provided with the integral ears extending upwardly at both sides near the ends, the integral overhanging cars at one end and a spring arranged at the end of the plate opposite the overhanging ears also provided with an overhanging projection.

2. An attachment or kit for photographic- ICC.)

ing upwardly, the ears out from the plate at one end and bent upwardly and then parallel with the plate and the loop cut and pressed upwardly, and the spring having the shank 15 extending beneath the loop and the overhanging ears at the free ends.
